"What's news in 2012" says (chapter 10 in the french edition), that the interface was completely re-built.
Unfortunately, your team has still a lot of work :
3 major bugs, imo, described here
have to be fixed, before a plane crashes because such behaviour in a CAD program.
2 - About the equation interface : when ENTER is entered, or when I dbl-click on something (often a global variable) to enter some parameter in an equation. if a sketch is opened, then, it closes.
As I generally enter more than one equation, and often with the sketch involved opened, I have then to re-open :
- the sketch
- but not only, because -3-
3 - When the equation interface is opened, impossible to open a sketch !!!!
So, the manip described at -2- implies to
- close at first the EI
- re-open at first the sketch, and then
- the EI.
4 - to use D_n@sketch_l works good, clicking on a dimension of a sketch, or on a previously defined dimension (left member of an equation).
It's another kettle of fish, if I want to click on a global variable to enter it in the right member of the equation !!!!
Even a paste and copy often don't works. Sometimes it works, often, it don't.
Compared to a previous version of the equation interface, I have not to open a zillion of windows to use equations, but your team has still some work, to make equations really user-friendly (which they would have to be, in any CAD program !!!)
